Month: September 2010

As a programmer working with other programmers, I’m usually contributing to an already existing code base and basically just adding new functions or extending their functionality and because I’m person who could be influenced by others opinions, I also could be influenced by others code and code formatting.

For a moment try to remember what your code looks like if you are writing brand new project and how, after a couple of weeks, this code is still nice and shiny even if you are working with 2 other programmers. Now back to reality where you working at old project where is lots of ugly code. Do you think that project start with ugly code? No, usually it doesn’t. So what changed that nice code to ugly one? Why even if all of programmers are good and writing nice code does, this happened? The reason is what’s called the broken windows theory.

Broken windows theory as the name suggests is about broken windows(not the MS Windows though). Imagine a street with nice houses and white fences. One day, somebody brakes the window of one of the houses. After few days, nobody has fixed the window because the house is empty, even though it looks very nice. One of your’s neighbours kids then brokes another window and because there is already one broken, nobody cares that much and time goes by. After couple of months the house has a broken fence, a couple of windows and garbage all around it. Soon this ugly house will affect the behaviour of your neighbours as the surrounding area deteriorates. You may start to care about cleaning sidewalk, but by then, the whole street has started getting ugly and uglier.

This story represent exactly what happen to you brand new nice code if somebody brakes the window and nobody fixes it.

So behave to your code as a good neighbour and try to leave your code in cleaner state than was before your changes, the whole area will be nicer as a result.

Yes that’s right, despite the fact that I’m employed by Unboxed I’m not working anymore. I’m going to work every day, programming some stuff but it’s not work for me anymore. Really.

I have had this feeling since I start working with Rails and this feeling became stronger when I came to London and joined Unboxed. I had heard about Agile and Scrum and I had tried to practise TDD and BDD before, but it’s really different here and now.

I joined the real world of Agile. I was so excited (and scared) when I had my first standup and my first retrospective. I’m still excited, because everyday is different. One day we have to do standup without our Product Owner (PO) because he is stuck at the tube. On another day, I was alone since everyone else was on holiday. Is it still a standup if only one developer and the PO are present? I think that it is, because the important thing is that I can tell him what is going on and another day of excitement can start.

Of course there are days when I’m tired, but you can be tired even after sitting on the beach with a Mojito in one hand and great book in the other. At the end of a tiring day at the office I look back and discover that I’m tired because I experienced so many new and interesting things.

So what am I actually doing if I’m not working? I’m a little bit scared that I might be dreaming. I’m scared I will wake up in my cubicle with PHP code (without tests) on my screen and without any slight hint of Agile or Scrum and Waterfall knocking on my door. So please don’t wake me; I like it as it is!

I start working for Unboxed Consulting at May 2010. Because we have got company blog I’m going to write more of my articles there, but this will be place where you can see the articles before official release date.
